KEY MESSAGES

- Unseasonably mild temperatures expected through the rest of the week and into next week.

- Precipitation chances remain limited through early next week, leading to higher precip deficits and worsening drought conditions.

SHORT TERM /THROUGH FRIDAY NIGHT/

Issued at 130 PM CST Thu Feb 12 2026

Northwest flow aloft across the Midwest and a mid-level trough situated over the Eastern U.S. is expected through Friday, leading to broad high pressure locally. Therefore we can expect a continuation of above normal temperatures and dry conditions. Forecast highs are in the lower to upper 50s (north to south) for Friday with overnight lows in the upper 20s to lower 30s.

LONG TERM /SATURDAY THROUGH WEDNESDAY/

Issued at 130 PM CST Thu Feb 12 2026

Friday Night through Saturday Night...A split in the polar and subtropical jet streams will allow for ridging to build to our north as a trough drifts across the southern Plains and Southeast. This will allow temperatures to remain above average in the 50s across the CWA as clouds fill in our skies Saturday morning. Even though the main dynamical support for precipitation will remain across the South, some isentropic upgliding in the mid-levels north of a warm front will permit some light rain to fall around the tri-state area of MO, IL, and IA. Accumulation will remain light during the day on Saturday, ranging from a trace up to 0.2 of an inch; NBM PoPs 20-50% south of I-80. Conditions improve Saturday night as high pressure sets up to our northwest and skies clear out.

Sunday through Monday night...The 500mb ridge to the north will remain in place, keeping us unseasonably warm and dry. Sunny skies are expected Sunday with some high-level clouds moving in on Monday ahead of a longwave trough digging into the western CONUS. Above average lows Sunday night with southwesterly flow could allow for record highs to be tied later on Monday at Dubuque and Moline (See Climate section for detail).

Tuesday through Wednesday night...A shortwave trough embedded in the longwave trough over the western CONUS will eject eastward across the northern Plains. As this trough becomes negatively tilted, a surface low will deepen over Nebraska aligned with the left exit region of a strong jet streak. There is uncertainty in the exact track of this developing mid-latitude cyclone with the ECMWF ensemble members landing in two camps: a more southerly track across Iowa or a northerly track in South Dakota. Regardless the northeast motion of this system will allow for strong southerly flow and WAA across the region with the LREF showing a 30-70% (North- South) chance of high temperatures reaching the 60s on Wednesday prior to the cold frontal passage Wednesday night. PoPs are currently limited to only 20-50% across our CWA Tuesday night into Wednesday morning as subsidence on the back side of the trough will dry out the low levels quickly during the day on Wednesday.

AVIATION /18Z TAFS THROUGH 18Z FRIDAY/

Issued at 1155 AM CST Thu Feb 12 2026

VFR will prevail through the period with decreasing clouds this afternoon and evening. Winds will remain light, generally under 10 kts.
